Hulls
End grain Basla/pre-preg glass Autoclaved cured DN Hull. For the DN Iceboat, construction utilizing pre-preg materials combined with class required wood is a first! Development has been on this approach for several years.
Benefits of this construction process:
- Increase strength and longevity of the hull
- Better structural protection for the sailor
- Consistent and repeatable manufacturing
- Commercially available at realistic cost
- Minimum weight
- cured at up to 90 psi and 260 degrees
Materials used in construction are 0.625" and 0.125" thick Baltek Super Lite AL60-10 select density end grain balsa , Epoxy prepreg "E" glass unidirectional tape, prepreg film adhesive supplied by YLA.
Curing takes place at 260 degrees for 4 hours while under vacuum and 90 psi autoclave pressure.
Tooling was made over a male plug of hull using Room temp epoxy tooling resin and surface coating materials. Fiber glass was used for the reinforcement fiber. Entire tool was post cure at 300 degrees after removing from plug.
The hull of the DN has very little effect on it's performance as long as it is minimum weight and most importantly "STRONG". This process delivers unequalled quality.
New For the 2001/02 Season
A newly designed Fuselage designed in collaboration with Bernd Zeiger. The new design was fully developed by 3D Cad program and then tooling produce by CNC 3 axis router in house. Apart from its accuracy the hull has many graceful curves and should be very secure to sail in.
